The Tatung TM17 17” CCTV Monitor is a feature rich video monitor designed for surveillance applications. A CCTV monitor is used to attach to your security DVR so you can best view the video your security cameras and DVR are capturing. Unlike a standard computer monitor, the TM17 is designed to work 24 hours a day all year long. A CCTV monitor is also vital because it will support the resolution of your cameras so you can always view the highest quality video. This video quality will come in handy when you are trying to playback video of an event.
